No

Explanation:

If the coil is accelerated parallel to the magnetic field, it means also that the force on the coil acts parallel to the field. For current to be induced in a coil, a basic condition must be met which is that the directions of force (acceleration) and the magnetic field must be perpendicular to each other. This brings about current being induced in a direction perpendicular to bothering the directions of the force acting on the coil and the that of the magnetic field. This current would flow through the coil in either a clockwise or anticlockwise manner.

Since the coil is accelerated parallel to the magnetic field, no current is induced in it.
